High pitched noise
Plugged it in and immediately heard a high pitched noise. Had it plugged in for several days and it never quit making that noise. Returned it to the store.

There is a high pitched squealing noise when you plug this into the outlet that I cannot stand. Guess it's going to sit unplugged until the battery dies because once you plug it in, it will drive you crazy.
